Be it known that LjT WILLIABf1(IENAST,

a citizen ofthe United States, residing in' the borough of Manhattan, in the city and State of New York, have invented certain new and useful Improvements .in'Surface-f Coating Mechanisms, of which' 'the following is a specification.

My present application is divided from my original application entitled Envelop machine which was filed on February 19th, 1907, and serially numbered 358202.

My application relates to surface 'coating mechanisms, and in order to clearly illustrate the invention, I shall describe the same with reference to mechanism for coating the surfaces of envelop blanks. u

The principal features of novelty in my invention relate to the means for applying the gum, the means for distributing the gum and the adjustability of :the various elements of the combination. These and-other features of-novelty will be readily understood from the description of the invention with reference to. the'accompanying drawlngs. y Y o In the drawings, Figure 1 is atop plan view of the complete surface coating mechamsm, Flg. 2 1s atransverse section of the 3isa same on line I-IH ofFigl, Fig.

per surface. The sliding frame is indicated at22 and has an underneath flange 23 which fits within the groove in the upper portion of the flange 21' so as 'to permit movement of the sliding frame 22 upon the stationary frame 20. A guide pin 24 projecting forwardfrom sliding frame 22 engages in a recess in the stationary frame 20 to'guide the sliding frame during its motion upon the stationary frame. The sliding 'frame also has a slot 25 through which a retaining I The retaining screw 26 is seated in the stationary frame 20, as clearly shown in Fig.3. In orderto resiliently draw the slidingframe 22 toward the forwardendof its path for a purpose which will hereinafter appear, a bolt 27 passes loosely through the sliding frame 22 and is seated at its forward end in the stationary frame 20. A spring 28 is confined by the head of the bolt 27 within a suitable spring recess which is formed in the sliding frame 22, as clearly shown in Fig. 1. The abovedes'cribed retaining screw 26 serves the purpose of preventing excessive rearward movement of the sliding frame 22 against the opposition of the spring 28.

Thesliding frame 22 has a downwardly extending flange 29 clearly shown in Fig. 8. This flange 29 has a grooved inner surface. This groove receives the outwardly projecting flange 30 of the U-shaped bracket 31 so as to permit forward and rearward movement of said U-shaped bracket relatively to the sliding frame 22. In order to resiliently draw the U-shaped bracket 31 toward the forward end of its path in the sliding frame 22, for a purpose which will hereinafter appear, a. spring device 32 fixed at its forward end to a lug 33 on the stationaryframe 20 and at its rearward end to a pin 34 on U- shaped bracket 31 is provided. This construction is clearly shown in Figs. 1 and 5 of the drawings. In order to adjustably limit the forward movement of the U shaped bracket 31, a flange 35 is formed at the rearward end of the flange 30 and is adapted to receive an adjustable stop pin 36 which abuts against the rearward end of the flange 29 of the sliding frame 22. The gum trough and distributing roller are mounted upon the said- U shaped bracket 31 as clearly shown in Figs. 2' and 14'. It will be seen that the U-shaped bracket 31 has a pair of upright supports 31 which have slotted porplace. The circular end 46 projects inwardly and upon this rests the forward end ofthe gum trough 47, (see Figs. 4 and 6).

The gum trough 47 does. not rest directly upon the stationary-trunnions, but is provided with lugs 48 which, as clearly shown in Fig. 6, have angular recesses and fit over the round portion 46 of the trunnions, their angular shape preventing binding. The

trunnions 43 are adjustably secured in the sl otted portions 38 so that the gum trough may be adjusted forwardly or rearwardly to any desired positiom and thus the trough moved bodily relatively to the gum distrib uting roller. y

The rear end of the gum trough 47 rests upon supporting bolt 49 which is adjustably secured in the lip 50 projecting from the bottom of the U-shaped bracket 31 and thus permits tilting the gum trough to any desired position relatively to the gum distributing roller 41. The gum trough can thus be set at any desiredposition relatively to the gum distributing roller 41. Scraping plates 51 are provided on the gum trough to scrape the ends of the gum distributing roller 41 to keep them suitabl free of gum.

Referring again to the sli ing frame 22, it will be seen that it is provided at its forward end with a journal bearing 52 (see Figs. 1 and 5). This journal bearing 52 receives a shaft 53 which has fixed on one end a gear wheel 54 in mesh with the above mentioned gear wheel 42 and on the other end a gear wheel 54. The shaft 53 has mounted on it the gum applying means, which will now be described. This means is illustrated in Figs. 1, 2, 9 and 10. .In the machine v a countersunk set screw 55.

which I have shown to illustrate my improved surface coating mechanism the object is to gumthe laps and flaps of envelops. To carry out this purpose the gum applying means comprises the following elements:

"A central roller 55 is adjustably fixed to the shaft 53, as clearly shown in Fig. 10 by The central roller 55 has a flattened side, upon which is mounted a plate 56. The plate 56 has resiliently secured to it by means ofretaining screws 57, a gum die plate 58 which bears the gum die 59 for gumming the flaps of the envelope in the particular machine described as an example of my invention. Any suitable resilient device, such as a spring, may be interposed between the plate 56 and the gum die plate 58, and the location of the roller is such that in rotation the gum die 59 comes into contact with the face of the gum distributing roller 41 and thus has the gum deposited upon it, while no other part of the central roller comes into engagement with the gum distributing roller 41. It is obvious that by the above-described construction the die plate is readil removable and may be substituted by ot er suitable plates to suit the particular need. The position of the central roller 55 being variable by means of its set screws fastened to the shaft 53, may also be adjusted to any desired position.

The lap gumming members are in the form of segment rollers 60 which are keyed on to slotted portions of the shaft 53 by the set screws 61 (see Figs. 1 and 2). It is thus evident that the lap gumming se ment rollers 60 are readily adjustable on t e shaft 53 to suit different widths of envelops. The segment rollers are so constructed that during rotation they come into contact with the gum distributing roller,- 41 for a predetermined portion of each revolution. This construction does away'with the necessity of providing a shifting means for the shaft 53, which has heretofore been commonl employed to obtain contact for a fraction of one revolution.

bottom 'roll 63. The shaft 62 is mounted inthe stationary frame 23 and has on its end the gear wheel 64 (see Fi 3) which meshes with the above-describe gear wheel 54. The shaft 63 is the driving shaft in the machine'and it will thus be seen that through the gear wheels 54 and 42 the shafts 53 and 40 receive their motion above referred to. The gear wheel 64 also meshes with a gear wheel 65 which is keyed to a shaft 66 directly above the shaft 63, and which carries the top roll 67 shown in Figs. 1 and 2. The shaft 67 has a pair of scoring bars 68. Scoring bars 68 are positioned in grooves formed in the upper roll 67 and suitably held by retaining lugs 69. The specific construction of these elements has been clearly described in my original 7 need not be gone into here urther than to show the general rinciple. As is well known these scoring bars are resiliently held in one side of their grooves by suitable.

of suitable camsfM and 7 5 shown in Fig. 1, all of which is constructed as fully described in my above mentioned originalapplication.

The operation of the scoring bars68 and gripping bars is to enable the latter to grip the envelop blank and carry it, past the gum applying means carried by shaft 53. In;

this operation the flap of the envelop rotates in engagement with the flap gumming die 59 and the laps ofthe envelop rotate in engagement with the segment. rollers .60. The

envelop blank is thus preparedfor folding, the gunnning having been accomplished in a;

single operation.
